Bill,
You can also try the Lincoln airport which is 2 1/2 hours from G-burg. The disadvantage is that they only have United and Northwest. Omaha has all the major airlines, but is 3 1/2 hours away from the airport, Denver is another 50 miles away. Kearney also is served by Frontier Express, but I think they are always evenly priced with North Platte. Bring an extra sick bag if you plan on landing at the small airports during a windy day. I personally do not like the G-burg acomodations, however North Platte is fine or Lexington is your next best choice.
Dick is correct on the food offerings, that area is probably the only part in the state that does not have several legendary local joints. IMHO. Dick, didn’t you find a decent Italian place in Cozad?
I have often wondered why no one has built a couple of condo rentals at WH. I would pay "normal" resort rates to stay around the course and bring my own food to cook. That is of course if my folks did not live 45 minutes away.
